What age do babies start sitting up. Most babies begin learning to sit up when they are four to seven months of age as their motor skills start developing gradually.In the third and fourth months, the head and neck muscles start gathering strength, helping the baby to raise his head and hold it in that position during tummy time [1] .n between five and six months, your baby usually starts to sit up with your help, holding his head in an upright position, keeping the back straight. He may even be able to sit for a second or so without taking any assistance from you, before toppling down after a while [1] .
By the time your baby is eight months old, she should be able to sit well without support (NHS 2013, Sheridan 2008). Nearly all babies can sit on their own by the time they are nine months old (NHS 2013, Sheridan 2008). How will my baby learn to sit up? While you can prop your baby in a sitting position almost from day one, sitting independently doesn't begin until your baby has head control.
